Sound like our tones. Only thing with ours, the admin programmed them to where the engine, ladder and ambulance all sound the same pitch. Can only really tell the difference when all them go off
What system is this? We use westnet and it's the same tone for every unit It's just a different color that comes out. there's at least one system in every room more depending on the size either on the ceiling or the walls.
I haven't seen this exact combination of technology, but there are station alerting systems that combine specific light colors with the unit that needs to respond.
